Final answer:
To rank the densities from greatest to least, they are organized by their numerical values. The correct order is 5.5 g/cm³, 2.8 g/cm³, 1.9 g/cm³, and 0.5 g/cm³, with 5.5 g/cm³ being the most dense and 0.5 g/cm³ being the least dense.
Step-by-step explanation:
We want to rank the given densities from most dense to least dense. The numbers provided are 5.5 g/cm³, 0.5 g/cm³, 1.9 g/cm³, and 2.8 g/cm³. To rank densities, we simply list them in order from the largest numerical value to the smallest, as density is a measure of mass per unit volume.
- 5.5 g/cm³: This is the highest density number on the list.
- 2.8 g/cm³: This comes after 5.5 g/cm³ in the ranking.
- 1.9 g/cm³: This is the third densest value provided.
- 0.5 g/cm³: This is the least dense number on the list.
Again, the ranking from most dense to least dense is: 5.5 g/cm³, 2.8 g/cm³, 1.9 g/cm³, 0.5 g/cm³.
